Windows 7 DWM has to restarted every time - Black desktop

[spcarso]

I was messing around with themes and changed a few settings (found a great background) and now after I restart, I have a black background and no icons on my start bar.

If I restart the DWM service, then all is well. However, next time I reboot I have to do that again.

Any thoughts?

I have the same problem after installing nVidias WDDM 1.1 drivers.
Installing the old 1.0 drivers solves the issue.
